To aZZ whom t may concern.'

Be it known that I, 4JOHN W.- HAsBUnG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Submarine-ProtectingDevices, of which the following is a specification.

This invention relates to an apparatus for protecting sub-marine craftsfrom capture.

One of the methods at present employed;

for disabling orcapturing sub-marine vessels is to set nets, of steelchains or: heavy cable, or other entanglements at advantageous pointsfor the purpose of enmeshing a submarine and preventing its escape. Netsof this character are placed across channels, entrances to harbors andsimilar places, where sub-marines are likely to pass. In using thismethod of capture it is intended that the sub-marine proceeding at speedwill force its way into the meshes of the net or entangle- I ment andits projecting parts, such as the deflecting planes, propellers, ruddersor conning tower, become entangled so as to prevent its escape.

The object of my invention is to provide a guard or protector carried onthe forward end of such a vessel which will prevent the vessel itselffrom becoming entangled with traps of this character. 1

Other objects of my invention are to provide such a guard which will actas a fender preventing the entanglement of the craft with the net and,kin the event the guard itself becomes entangled and operator within thecraft may release the same so that the vessel may back away and leaveits guard in the meshes of the net.

Another object of my invention is to provide such a guard whicln'whennot in service may be folded backwardly against the sides of the vesselto offer less resistance to the water and not hamper the movements ofthe craft.

Other and further objects will become readily apparent to those skilledin these matters from a consideration of the following specification anddrawing, wherein:

Figure 1 is a side elevation of a sub-marine craft showing my guardattached thereto and in collapsed or folded position.

Fig. 2 is a horizontal section through the bow of such a craft showingmy guard in its extended position.

Fig. 3 is an end elevation of a sub-marine Y craft showing my guard inextended position.

line 4-4 of Fig. 2, and;

.Fig 5 is a transverse vertical sectional viewV through the guard. Y

In the drawings I have illustrated an embodiment which my invention maytake, a simple protector being provided for attachment to the forwardvend of a sub-marine craft which may be readily folded backward out ofthe way or can'be detached in thi-event it becomes enmeshed in a trap orne tions and changes may be made therein and that the specific formillustrated is merely suggestive of a preferred form. l

Referring now to the particular embodiment illustrated the numeral 10indicates the-body of a sub-marine craft on the'bow or nose section ofwhich is secured a plate 12 carrying at itsy center a forwardlyextending squared post 13. An internally squared tube 14 telescopes overthe post 13 and is provided at its forward end with an enlarged head 15from which radiate and to which are pivotally secured a plurality ofarms 16. In thepresent instance I have shown iive arms projectinghorizontally and upwardly beyond the transverse outlines of the craftleaving beneath the horizontal section an unobstructed area to preventinterference with discharge of torpedoes from the'torpedo tubes 17. j

The arms 16 are foldable back againstthe sides of the sub-marine asindicated in Fig. 1, this movement being controlled by a series oftoggle locks comprising bars 18, 19 pivoted together at their inner endson bolts 20, the forward end' of bar 19 being pivotally connected withthe rod 16 and the rear end of bar 18 pivoted to a flange extension 21on the rear end of the tube 14.

The movement of the legs 18 and 19 for extending or collapsing the guardis secured by the use of a series of rods 22 pivoted, as at 23, to thebar 18, and at their inner ends pivoted, as at 24, to a block 25,slidable within the tube 14. I/Vhen the block 25 is in its rearwardposition, as* indicated in Fig. 2, the rods 22 brace the toggles andsecurely lock the arms 16 in their outwardly extending position.Movement of the block 25 forwardly within the tubes 14 first breaks thetoggle connections and then draws the Fig. 4 is a transverse sectionalview on the l r It will be obvious that varionsmodica- Y rod 18 inwardlycollapsing the guard back against the sides f the sub-marine as'indicated in dotted lines in -Fig. 2. n

For the purpose of operating the sliding block Q5 from the interior ofthe craftr l have axially perforated the post 13, and extendedtherethrough a rod 26, thread-ed at its' forward end for engagement withthe threaded opening in the slide block 25. A heavy coil spring 27surrounds'the post 13 and serves as a cushion or b'umper'between thenose of the craft and the rear endof tube le-,

Normally it is desirable to hold` the guard in position upon the postand this is accomplished by means of a latch 28 extending' through thenose" ofl the sub-marine and carrying at its forward end a hook 29 whichengages the collar 2l to retain the same upon the post. A handle 30 isprovided on the end of the latch 28 within the sub-marinefor actuatingthe same.

l have also providedan electrically actuated signal comprising areciprocable plunger 3l extending through the nose of the submarine andinsulated therefrom, its forward' end being adapted for engagement bythe collar 2l if itis forced backwardly against the coil spring 27, andits rear end serving to close contacts 32 of an electrical circuit 33including a bell Lor other signal 3%.

In operation the craft on approaching` a danger Zoner extends its guardor'protector by drawing inwardly upon the rod 26. As soon as the togglehas been set the rod 26 is rotated until it is disengaged from thesliding block 25, thus freeing the guard from` all connection with thecraft other than that provided by the latch 28. In the event the craftruns into a net or other form of trap,l

the forwardly extending protector will first engage the same and beforced backwardly against the bumper spring 27 Closing the electricalsignal circuit and warning. the operator to reverse his engine.A Onreversal of the propeller the backward movement of the submarine willtend to draw the guard orl protector away from the net or trap.v Inmtheevent, however, that the guard has beenfimmeshed or caught in the trap,the operator then releases the latch 28 and permits the sub-marine toback away, leaving its guard in the trap. y

Vhereas in the drawings I have illustrated and described a singleembodiment of my"inven`tion it will be obvious to those familiar withthese matters that many changes and alterations may be made thereinwithout departing from the spirit thereof or the scope ofthe appendedlclaims.

Having described my invention, what l claim is l. A'safety device foi`vessels comprising a framesecured to the bow of the vessel, means'forcollapsing the frame and means operable from within the vessel fordetaching the frame therefrom.

2. A safety Ydevice for vessels comprising a frame secured to the bowofthe vessel and extending beyond the sides thereof, means operable fromVwithin the vessel for detachingl the frame therefrom,'and meansoperable from within the vessel for ,collapsing the frame.

3. A safety device for sub-marine vessels comprisinga post secured'tothe front end thereof, 'a frame slidable on Asaid postand extensibletransversely to project beyond the sides of the vessel, means operablefrom within the sub-marine to fold the frame backward against. the sidesthereof, and releasable means for retaining the frame upon the post. Y

4. A safety device for sub-marine vessels comprising a post .securedtothe front end thereof, a. frame slidable onsaid post and extensibletransversely to project beyond the sides of the vessel, aspringinterposed between the frame and the vessel to resiliently holdthe frame in its forward position, means for releasing the frame fromthe post, and means operable on the rearward movement of the frameagainstthe spring ,for initiating a signal within the vessel.

In testimony whereof I hereuntoset my hand. Y f
